Question

For a group of positive charges, which of the following statements is correct?

• A. Net potential of the system cannot be zero at a point, but net electric field can be zero at that point.
• B. Net potential of the system at a point can be zero, but net electric field can't be zero at that point.
• C. Both the net potential and the net electric field can be zero at a point.
• D. Both the net potential and the net electric field cannot be zero at a point.

Hint:

- The electric potential is a scalar and cannot be zero for a system of only positive charges.
- The electric field is a vector and can be zero if the fields cancel out symmetrically.
